IMPROVEMENT IN WATER-METERS.

dlp .tlgehnlt naman in time tettett ateni Be it known that I, GERARD SIcKnLs, of Boston, inthe county of Sulfolk, and State of Massachusetts, have invented a newand useful Improvement in WatenMcters, of which the following is afull, clear, and exact description, reference being had to the accompanying drawings, making a part of this specificati-on, in lwhichx Figure 1 represents a longitudinal vertical section of a water-meter embodying my improvements. ligure 2 is a transverse vertical section of the same; and i Figure 3 is partly a plan view and partlyhoriaontal longitudinal section.

Figure 4 isa modicationof the device for operating .the slide-valvc piston.

Similar letters indicate likeiparts in the several figures The. object of my invention is to produce a simple, cheap, and accurate apparatus` for measuring a supply of water; and the invention consists in effecting the entire' motion of the valve by .shifting the hearing roi'l the foot of a prop attached to-,the 'under side of the valve-piston', so thatfas the foot'of the said prop is moved towards the centre of its track, the piston'is elevated, and after the said foot passes the centre, the pressure of' the water upon the piston will force the'foo't of the prop to the opposite end of its track, thus inclining itin the' opposite directiemand causing the upper end of theprop to push the valve in the opposite direction. VThe prop of the valve-piston-extends down into the cylinder, -so that it can he operated uponA by the .direct action of the cylinder-piston. I *A l* Referring to the drawings, a represents a cylindrical casing, provided with heads,b b, at either end.- Within the said cylinder are two pistons, e c, connected to each other by a bar, d, provided with a slot at,.itsA central portion, through which projects the lower end of the propo. g'is the induction-chamber, over which is fitted the cap f, attached to the upper portion of the cylinder a. L is the inlet-opening to the induction-chamber g, and z' is the outlet at the centre of the side of the -cylinderfrn as' shownin iig. 2. m i's a. slide-valvc ttedon a seat, e, forming a part of the cylinder. It is sui-mounted by a valve-cylinder, l, nwhich is fitted a. pis-ton, Je.

n n are the ports castin the cylinder. 'lloI the under side-of the valve-pistonlc is hinged o r/pivoted a prop, o,

consisting of a metal bar, extending downwards through the slot r, in the connecting-har 0l of the cylinder pistons. At a point somewhatabove the connecting-bar d, it is provided with rollers pp on either side, which have their bearings in corresponding seats, g q. The said seats curve upwardly at their ends, as seen in iig. 1., so as to arrest the progress ofthe rollers pp of the prop o, at the limit of the motion ofthe latter in each direction. s s are uprights which support the seatsg g of the rollers 2Q 1o. Y.

The prop o, instead of being lsu'pported by rollers upon-the seats q g, may 'be pivoted to an auxiliary prop, o', which is hinged or pivoted to a proper supporting piece attached to the centre of the lower inner surface of' the cylinder a, as shownin fig. 4; the upperend of the said auxiliary-prop 0, resting at each alternate .throw of the cylinder-piston against the opposite sides of .the openingin the upper portion of the'cylinder a, so as .to

cause the prop o to shift its point of bearing to incline in opposite directions, and only move'the valve after reaching the hearing-points. i

An indicating-device for determining the quantity ef water passing ,through the meter, may be arranged in any suitable manner onthe top of the cap fgso as to be ope-rated by the verticaltmotion of the valvepiston.

The operation is asiollows: The wat-er being -introducedinto 'the inductionchamber y', through the inleti opening h, will, by its pressure, force the valve m upon its seat, and also'the piston downwards; at the s'amey time passing downwards through the ports alternately at either side, will operate' the' cylinder-piston o 'c in the usual manner, and, passing to the centre ofthe cylinder, between the pistons, will be ejected through the' outlet c', as indicated by the arrows. During the motionoi' the piston, vthe prop o, extending down through the open; ing r in the connection-bar d, is moved along until the foot ot`- the prop has passed the perpendicular centre,- elevating the valve-piston while assuming the perpendicular, when the pressure upon the -Valvepiston will cause the foot of the prop to travel in a direction to the opposite bearing. When Vthe prop has changed its inclination in an opposite direction," its upper end will he forced forwardand downward, thus imparting the, propermotion 'to the valve to changethe ports.

What I claim-asfmy invehtion. and' desire to secure by Letters Patent, s- 1. Eectng the entire motion of the valve by shifting the bearings of the foot of the prop o, attached to thefunder side of the valve-piston, substantially as set forth, v

2. `.hbztendingthe prop of the vulve-piston down into the cylinder, so that it can be operated upon by the drectvmotion-of the cylinder-piston. l

The Vcombination of the valve-piston c, themovztble prop 0,' and the connecting-bar d, substantially as and for the purpoe described. l

In testimony whereof, I have sgnodmy name to this specification io the presence of twosubscribing witnesses.
